■When the outside temperature exceeds 75°F (24°C) and the air conditioning sys-
tem is on
●In order to reduce the air conditioning power consumption, the air conditioning
system may switch to recirculated air mode automatically. This may also reduce
fuel consumption.
●Recirculated air mode is selected as a default mode when the “START STOP
ENGINE” <“POWER”> switch is turned on.
●It is possible to switch to outside air mode at any time by pressing .
■Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and auto-
matically switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.
■Micro dust and pollen filter
●In order to prevent the windshield from fogging up when the outside air is cold, the
following may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The dehumidification function operates.
• The operation cancels after approximately 1 minute.
●In rainy weather, the windows may fog up. Press .
●In extremely humid weather, the windows may fog up.
●The pollens are filtered out even if the micro dust and pollen filter is turned off.
■Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to priori-
tize fuel efficiency:
●Engine speed and compressor operation controlled to restrict heating/cooling
capacity
●Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
●Adjust the fan speed
●Turn off Eco drive mode
■When the outside temperature falls to nearly 32 °F (0 °C)
The dehumidification function may not operate even when is pressed.

■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into and
accumulate in the air conditioning system. This may then cause odor to be emitted
from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air modeprior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immedi-
ately after the air conditioning system is started in automatic mode.

■Customization
Settings (e.g. exhaust gas sensor sensitivity) can be changed.
(Customizable features →P. 8 6 3 )
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.

NOTICE
■Humidity sensor (if equipped)
■To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is off.
In order to detect fog on the windshield, a
sensor which monitors the temperature of
the windshield, the surround humidity, etc. is
installed. ( →P. 3 6 1 )
Follow these points to avoid damaging the
sensor:
●Do not disassemble the sensor
●Do not spray the glass cleaner on the sen-
sor or subject it to strong impacts
●Do not stick anything on the sensor
